With reference to your article I have the pleasure to tell you the history of my grandfather Alfredo Di Lelio, who is the creator of “Fettuccine all’Alfredo” (“Fettuccine Alfredo”) in 1908 in the “trattoria” run by his mother Angelina in Rome, Piazza Rosa (Piazza disappeared in 1910 following the construction of the Galleria Colonna / Sordi). This “trattoria” of Piazza Rosa has become the “birthplace of fettuccine all’Alfredo”.
More specifically, as is well known to many people who love the “fettuccine all’Alfredo”, this famous dish in the world was invented by Alfredo Di Lelio concerned about the lack of appetite of his wife Ines, who was pregnant with my father Armando (born February 26, 1908).
Alfredo di Lelio opened his restaurant “Alfredo” in 1914 in Rome and in 1943, during the war, he sold the restaurant to others outside his family.
In 1950 Alfredo Di Lelio decided to reopen with his son Armando his restaurant in Piazza Augusto Imperatore n.30 “Il Vero Alfredo” (“Alfredo di Roma”), whose fame in the world has been strengthened by his nephew Alfredo and that now managed by me, with the famous “gold cutlery” (fork and spoon gold) donated in 1927 by two well-known American actors Mary Pickford and Douglas Fairbanks (in gratitude for the hospitality).
See also the website of “Il Vero Alfredo” .
I must clarify that other restaurants “Alfredo” in Rome do not belong and are out of my brand “Il Vero Alfredo – Alfredo di Roma”.
I inform you that the restaurant “Il Vero Alfredo –Alfredo di Roma” is in the registry of “Historic Shops of Excellence” of the City of Rome Capitale.
Best regards Ines Di Lelio
